Vraell (real name Alessio Scozzaro) makes music in the quietness of spring and summertime dusk. For that one hour of cerulean sky, the London-based musician’s ideas come to life, illuminated by the poignancy of evening as it turns to night. He wrote much of his forthcoming debut album “Once a Blue Hour” during these bewitching moments, filling the silence with music that delves into the darkness and beauty of healing. With his deft guitar skill at the center, Once a Blue Hour paints an intimate picture of letting stillness birth something new.
